Abstract: A tie is provided for holding together the parts of a fractured bone. The tie includes an elongate, flexible, plastic strap provided on at least one face thereof with ratchet teeth and provided at one end thereof with an aperture through which the other end of the strap is capable of being passed. The aperture has a pawl adapted to engage the ratchet teeth. The strap is provided on that face which, when the end of the strap is passed through the said aperture, is the inner face, with at least one protrusion. Alternatively, to the use of protrusions on the strap, or in addition an elongate plate is positioned adjacent the fractured bone and straps are passed through slots in the plate. The plate then spaces from the bone.
